Final answer:
In Bach’s Orchestral Suite No. 3, the Air is slow and stately, thus matching with description A, and the Gigue is fast and lively, corresponding to description B. Descriptions C and D do not apply to these pieces.
Step-by-step explanation:
The question asks to match the descriptions to either the Air or the Gigue from Bach’s Orchestral Suite No. 3. The Air, also known as Air on the G String, is characterized by a slow and stately pace, making it the correct match for description A) Slow and stately. On the other hand, the Gigue is a lively, fast-paced dance form, which aligns with B) Fast and lively. Description C) Percussive and rhythmic and D) Smooth and flowing do not traditionally describe the Air or the Gigue from Bach’s Orchestral Suite No. 3. Therefore, they are not applicable here. The descriptions provided in the question are strongly suggestive of the inherent qualities of the respective compositions, where the Air exhibits a serene and dignified quality, while the Gigue is effervescent and brisk.
